A generic Storage system for blobs.

Required Methods

fn put_from<R: Read>(&mut self, key: &str, r: &mut R) -> Result<usize, Error>

Save the content of r into the storage system with the given key.

fn get_to<W: Write>(&mut self, key: &str, w: &mut W) -> Result<usize, Error>

Read the contents of the blob with the given key into the given writer.

fn prefix(&mut self, prefix: &str) -> I

Find all blobs that have the given prefix and iterate over them.

fn delete(&mut self, key: &str) -> Result<(), Error>

Delete the blob with the given key.

Provided Methods

fn put(&mut self, key: &str, data: &[u8]) -> Result<(), Error>

Similar to put_from but uses the give data instead of a reader.

fn get(&mut self, key: &str) -> Result<Vec<u8>, Error>

Similar to get_to but reads the contents into a byte vector.

fn remove(&mut self, name: &str) -> Result<(), Error>

Similar to delete but it does not return an error if the error is NotFound.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
